In answer to a question that was taken on notice during the estimates hearings, the department of immigration provided a table identifying the cost per detainee per day for each facility. Villawood cost $190 per detainee per day and Christmas Island cost $2,895 per detainee per day. I want to know what the cost is per detainee per day for somebody to be kept in Nauru, how that differs between Nauru as it was at the time of the budget and under the merged facilities in Nauru, and what services and facilities detainees at these two centres receive. If the reasons for the difference could be identified in a reference to the costs per detainee, that would be of assistance.
